Cisco QSFP-40G-ER4 Compatible Transceiver 40GbE QSFP+ 1310NM 40KM DOM Dual LC

Top-trans QSFP+-40G-ER4 is designed for data center and Enterprise wide-area interconnection. This QSFP+ module provides high speed, low latency, and reliable optic connection for service distribution within a wide area region and seamless communication.

This QSFP+ module is equivalent to Cisco QSFP-40G-ER4, with excellent interoperation on the Cisco Catalyst 9600 series switches.

It is fully compliant with the industry MSA agreement for 40GBASE-ER4, using WDM technology to couple four individual 10Gbps CWDM waves into one 40Gbps 1310NM optical path. This QSFP+ module is made up of four CWDM DFB TOSA and APD ROSA for enough link budget to 40KM transmission over single mode fiber with LC duplex connectors and an QSFP+ Interface for port contact with switches, servers and NIC. With the Built-in DOM/DDM function, network maintenance can monitor its working statuses like operation temperature, voltage, bias current, RX power, and TX power for network diagnostic and adjustment.
